Many aspects of the Vedas can be corroborated scientifically and veiwed as plainly  observed  objective sciences . Explanations of many kinds of unexplained phenomena  are given , things that the world of scientific materialism and Darwinian hypothesis have no explanations for . The simple explanations of the origins of the information in the DNA codes and the highly organised engineering along with informational exchanges that take place whilst every single species of life is built from its beginning where a consciousness particle is injected into a womb till its completion are explained , of course molecules don’t move towards life and the information of the codes logically imply creative energies , the energies spoken of in the Vedas .

Also..

Out-of-body experiences (OBEs) are 

recognized in scientific literature as a relatively common, albeit not fully understood, phenomenon that affects an estimated 10% to 20% of the population at least once in their lifetime. While they are often described in spiritual terms, researchers generally define them as complex dissociative or perceptual experiences rather than a physical departure from the body. 

The Vedas have the full explanation in the third Canto of the Srimad Bhagavatam , and in other parts of the Vedas .

When you dream at night, you are speaking , hearing, and acting sensually, but you have forgotten of the other body lying in bed or your daytime relationships .This ethereal energies that entraps the minds energies and creates forms of both subtle and gross matter are given explanations. The causes of the transmigration of the consciousness into another body is the mind and its works .

Sciences have authority,  you either accept someone like Richard Dawkins or Lea Cronin or you accept Vedic scholars,  the same process of acceptance of authority of scholarship are in each culture of Sciences.

But how do you know they know ?…. the Vedic authorities are based on objective sciences and strong evidence of logic ,this can be clearly examined and studied .Those authorities of scientific materialism and Darwinian hypothesis appear to all sense and purposes as highly speculative and without logic .
